The Method of Emergency Message Retransmission for the Disaster Vulnerable People

In the event of a disaster, obtaining information about the disaster quickly and accurately is an important matter that not only reduces the associated economic damage, but also leads to survival. We suggest the method to more efficiently utilize emergency messages transmitted to smartphones through telecommunication networks. The method we propose is to process the emergency message received by the smartphone according to the emergency level and send it back to the smart watch and earphone connected via Bluetooth. This enables the disaster vulnerable people, such as the elderly, children, foreigners, and visually impaired people, to quickly receive disaster information.
